OpenID4VP - problem presenting claims from multiple namespaces of mso_mdoc

[dkulic]

Description:

When performing an OpenID4VP presentation using an mso_mdoc credential that includes multiple namespaces, if the requested claim is from any namespace other than the first, the resulting response does not include the requested claim.

Steps to Reproduce:

Issue an mso_mdoc credential with multiple namespaces (e.g., namespace1, namespace2).
Create a presentation definition that requests a claim from namespace2.
Initiate an OpenID4VP presentation using the EUDI Wallet Android app.
Inspect the response payload.

Expected Behavior:

The response should include the requested claim from namespace2, along with the correct namespaces mapping.

Actual Behavior:

The response omits the requested claim entirely when it is from a namespace other than the first one in the credential. This results in an incomplete or invalid presentation.
